MILK-REFRIGERATIN G APPARATUS.

To all whom it may concern:

Be it known that I, CHARLES N. GILLE, a citizen of the United States,residin at Omaha, in the county of Douglas and tate of Nebraska, haveinvented certain new and useful Improvements in Milk-RefrigeratingApparatus, of which the following is a specification.

This invention relates to an improved milk refrigerating apparatus foruse in connection with the pasteurization of milk, and has for itsobject to provide an apparatus by use of which, milk, after it has beenheated to a high degree of temperature, may be quickly and reliablycooled.

The invention has reference to a construction whereby milk may beconducted upon curved surfaces by gravity, and exposed, during itspassage, to a moving liquid refrigerant movin in a direction opposite tothe movement the milk, and movin in a vertically disposed jacket,closely ad acent to the passage ways of the milk.

The invention includes the manner of forming the interior and exteriorsurfaces of the refrigerating jacket, and means for directing the flowof the refrigerant, whereby operation may be efi'ective for cooling milkquickly, and Within a small compass or space, and requiring aconstruction ofparts attended with slight,-c0mparative expense.

The invention consists of'the novelconstructionand'arrangement'jof'gparts as (1.

scribed and claimed,'and as illustrated in the accompanying drawing,Where'in,

Figure 1 is a vertical,' s ide view, partly b ok away, mi k. reiri' a nmi ramsm S de 'qb e si ee ei sd .F s- -i .:aitan vers a i a1. omewhat elarged; of 1 the a fp'arat l s 0' 'i pp P r eing-f r ke The severalparts ofth e a paratus" may be constructed to advantaged use ofsheetmetal, except the distributing or intake pipe and waste. pipe, althoughI do not wish to limit .myself to this material. n "Referring now' tothe dr'awin for a more particular description, nume'ra '1 indicates asuitablejframe, com rising parallel, upright end-sections Wand 3,"andsaid sections may be formed substantially A-shaped to advantage.

milk tank 5, the bottom of said tank having a depressed portion orlongitudinal trough 6 with a perforated bottom, said trough being midwaybetween the sides of the tank.

I provide a refrigerating jacket 7 adapted to contain a fluidrefrigerant under ressure, said jacket being, generally spea ing, anattenuated, rectangular receptacle. It is mounted and disposedvertically upon the frame and is provided with uniform side walls, eachof its side Walls being formed with a plurality of longitudinal,outwardlycurved wall-portions 8 disposed horizontally and parallel, withreference to each other, and connected by an intervening web 9,wallportions 8 of each of the sides of the receptacle being disposedopposite to each other, the Webs also being disposed parallel andopposite to each other, and closely adjacent. As thus described, each ofthe o positely-disposed, outwardly-curved wa ls 8 provide longitudinal,horizontal chambers 10 extending the entire length of the jacket, andthe oppositely-disposed webs provide narrow longitudinal passageways 11between said chambers, and as is apparent, if an exit way is provided inthe wall. of the uppermost chamber 10, a liquid refrigerant, when forcedwithin the lowermost chamber 10 will move upward through all ofchainbers 10 and passageways 11,the entirejack'e't at this time, beingfilled with the liquid refri erant. i

t regular longitudinal intervals adjacent to the upright walls 12'and13, in the bottom 14 of trough 6 are provided the series of aliningfperforat-ions indicated, respectively, at "15 and 16, through 'whi chjs me y P 531, th ."fi fi b s regular, since the bottom th horizontal andthe perfoija ons'thereln,

uniform. Jacket 7 is disposed beneath tr gh 6, and each of the curvedfwalls8 of thjegjacket is disposed belowone of the seriesof perforations15 or :16, 'a'nd inoperation the milk will be equally dividedponehalf ofthe contents passing;;do wnwarduponQeach of thes'ides of ja'cke't7.

The downward movement of milk upon the jacket will be retarded by reasonof the outwardly curved walls 8 over which it must move before itreaches the receiving tank 17, and it will be noted that the exteriorsurface of the jacket is such, that while the downward movement of themilk will be retarded, there are no wings, terminal walls or unevensurfaces to cause churning or precipitation. i After leaving the jacket,the milk passes into the receiving tank by flowing downward upon thesides of the vertical sheet or flow-plate 18; and this plate may beattached in any convenient manner to the lower terminal of the jacket,and its use tends to prevent precipitation or churning of the milk.

A liquid refrigerant, under pressure, may pass through supply pipe 19.This pipe has a horizontal stem 20 disposed in the lowermost chamber 10of jacket 7; and at 21 are indicated perforations formed in alinementand at regular longitudinal intervals in the lowermost part of its wall,so that there may he an equal distribution of the liquid rofrigerantthroughout the entire length of the jacket.

At 22 is indicated a waste pipe provided with a horizontal stem orsection 23 traversing the uppermost chamber 10 of the jacket, and in theuppermost part of its wall are provided perforations 24:, theseperforations being formed in that part of the stem or section disposedwithin the water jacket; and, in practice, the liquid refrigerant willhave a movement upwardly through the jacket, from the lowermost to theuppermost parts of its interior. The movement of said liquid istransversely of the jacket, thereby tending to provide a uniformity inthe distribution of the same, the upward movement being at the ends aswell as the middle of the jacket; and during these movements heat willbe absorbed from the milk while the latter passes downward upon theexterior; surface of the jacket.

In order that the milk may be kept clean during operation, jacket 7 ishoused within chamber 25. The top and bottom of this chamber isprovided, respectively, by tanks 5 and 17; and upon the upper part ofthe rame are secured p1ates2 to pro ide. n walls for said'ehamber,End-sections 2 and 3 are pro ided with horizonta ..,e o tri s 28, thesestri "sbf ing disposed atfah altitude below jacket ,and theyope'rate assu ports for the end-flanges 29 of the'remova 'le' receiving tank; 17. j

I provide side-plates or covers 30, and their lower edges are adaptedto'have seatings u on brackets 31, these brackets being secure upon theouter sides of each of the end sections, adjacent to cross strips. 28.

Plates 30 provide side walls for chamber 25 and they have an areasufiicient to cover the space intermediate the end sections and betweentanks 5 and 17. They may be conveniently removed, and the sides of thejacket are then accessible for cleaning purposes; and when placed inposition, the plates require no fastenings but are held by their ownweight since they rest upon t upwardly convergent sides of the A-shapeend-sections Milk pasteurizers or sterilizers are no quite generallyused by milk dealers, and i such use it is desirable, after the temper:ture of the milk has been raised to the ri quircd degree of heat, toquickly reduce tl tei'i'iperature. The construction for th purpose asherein shown, provides a C01 venient, effective and comparatively inc:pensive apparatus. City water under pre: sure is the most economicalrefrigerai known for this purpose, and when used i connection with saidapparatus, is convex ient for effectually reducing the temperatur Havingfully explained the several parl and their uses, a further descriptionis n( necessary.
